python - 获取视频剪辑的最后一帧并使用 moviepy 延长 10 秒

Question

我正在使用 moviepy 来编辑一些视频剪辑。我想播放原始剪辑的最后一帧 10 秒，这样我就可以在上面显示一些文本。我尝试使用

将最后一帧转换为视频

clip.to_ImageClip(t=clip.duration).set_duration(10)

但失败了。

有人知道为什么吗？以及任何可能的解决方案。

import moviepy.editor as ed
import os

content=ed.VideoFileClip(path)
myclip=content.to_ImageClip(content.duration).set_duration(10)
myclip.write_videofile(path)

MoviePy 错误:

failed to read the first frame of video file C:\my\test.mp4. 

That might mean that the file is corrupted. 
That may also mean that you are using a deprecated version of FFMPEG. 
On Ubuntu/Debian for instance the version in the repos is deprecated. 
Please update to a recent version from the website.

我也面临同样的问题，但是，下面的代码对我有用:

clip = VideoFileClip(path)
frame_t = clip.duration - 1
ext_clip = clip.to_ImageClip(t=frame_t, duration=4)
ext_clip.write_videofile("sample4.mp4", fps=24)
